Installing PHP eAccelerator from source

Requirements

     * php4 or php5
    * autoconf
    * automake
    * libtool
    * m4 

eAccelerator only works with mod_php or php in fastcgi mode. It can’t be used in cgi or cli because eAccelerator needs to set up shared memory, and this can only be done when all php instances that need to access it are forks of the first process.

Installation
download  eAccelerator

Download the tarball file from the source  

cd /usr/local/src/
mkdir eacp
cd eacp
wget http://bart.eaccelerator.net/source/0.9.5.2/eaccelerator-0.9.5.2.tar.bz2
bunzip2 eaccelerator-0.9.5.2.tar.bz2
tar xvf eaccelerator-0.9.5.2.tar
cd eaccelerator-0.9.5.2
